--------------------------------------------
Summary: Mock table 'EMPNULLABLES' should allow nulls in all
non-pk columns
Key: CALCITE-4075
URL: https://issues.apache.org/jira/browse/CALCITE-4075
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Stamatis Zampetakis
Currently Mock table 'EMPNULLABLES' allows nulls in almost every column. It
does not allow nulls in the primary key which is expected and the column
'ENAME' that is unexpected.
I realized that 'ENAME' column was declared as not nullable after debugging for
quite some time a test where I was wrongly assuming that all columns of the
table were nullable.
To avoid this kind of confusion in the future I propose to make 'ENAME' also
nullable. The impact on existing tests is minimal.
